Detailed Documentation

Read-write Sparse Matrix Iterator.

The class is similar to cv::SparseMatConstIterator, but can be used for in-place modification of the matrix elements.

Construction

SparseMatIterator()

the default constructor

SparseMatIterator(SparseMat* _m)

the full constructor setting the iterator to the first sparse matrix element

SparseMatIterator(
    SparseMat* _m,
    const int* idx
    )

the full constructor setting the iterator to the specified sparse matrix element

SparseMatIterator(const SparseMatIterator& it)

the copy constructor

Methods

SparseMat::Node*
node() const

returns pointer to the current sparse matrix node. it.node->idx is the index of the current element (do not modify it!)

SparseMatIterator&
operator++()

moves iterator to the next element

SparseMatIterator
operator++(int)

moves iterator to the next element

SparseMatIterator&
operator=(const SparseMatIterator& it)

the assignment operator

template <typename _Tp>
_Tp&
value() const

returns read-write reference to the current sparse matrix element
